The 140 mm fan acts at the three speeds as already on the other radiator strengths. Finally, let’s look at the absolute values in the bar graph.

Frequency spectra at different speeds

Finally, let’s look at the frequency analyses of all measurements for all fans measured and all three speeds tested. The graphics and sound samples (at 1000 and 1200 rpm) speak for themselves.

500 rpm

For this low speed, we did without a special sound sample, because the fan is almost inaudible.

1000 rpm

1200 rpm (100%)
